Do you need to change intake manifold gaskets?
Just using 87 octane in the tank. Completely-steady idle.

This would apply to any LS-derivative GM V8.
Can you clean the intake manifold of a GM V8?
Fuel additives and cleaners will clean from the heads-down, you can clean the throttle body, but you won’t be able to get everything out of the manifold itself. This is at 85k miles, and any other GM V8 is going to be the same deal (worse if you have not been running a catch can since very early).

How to remove intake manifold gasket on Silverado truck?
Remove the throttle body and air tube. On the newer trucks, there’s no coolant lines running through the throttle body and the throttle position is all-electric, no manual cables. Gas line comes off easily, you can relieve the pressure on the passenger side valve first (just remove the cap and push in).
